At Shenzhen Kongfar Technology Co., Ltd., every module used in our solar-powered CCTV systems and off-grid solar power kits is verified on a sun simulator with I-V curve tracing and calibrated current/voltage (Voc/Isc/Vmp/Imp) tests under STC conditions. Technicians validate power tolerance, series resistance, and hot-spot risk, then bin modules to guarantee consistent strings for PoE cameras, routers, and IoT sensors. The data are tied to a unique QR/serial for traceability across our ISO 9001 process, supporting public tenders that require documented performance for smart agriculture, telecom base stations, pipeline surveillance, and river monitoring.

We also run sample checks at NOCT to simulate real off-grid environments, confirming MPPT tracking windows for our controllers and the expected yield for LiFePO4 battery charge profiles. Combined with insulation & ground continuity tests, this regime reduces field failure rates and ensures stable output for 24/7 solar surveillance systems. For buyers seeking a China solar power system factory with verifiable quality, our IV reports, CE/EMC/LVD/RoHS documentation, and acceptance criteria provide the compliance backbone for scalable, plug-and-play OEM/ODM projects.
